在慢性疼痛患者中使用了几种自我报告的测量方法来确定6种活动模式：疼痛回避、活动回避、任务持续、过度持续、疼痛持续和起搏。评估起搏的工具应该包括三种起搏行为(将任务分解为较小的任务，经常短暂休息，放慢速度)，每一种行为都与一个目标有关(增加活动水平，为有价值的活动节省能量，以及减少疼痛)。本文提出了活动模式量表(APS)，对这6种活动模式进行了评估。研究1包括291名患有慢性疼痛的参与者，并使用验证性因素分析测试了3个结构。具有最好拟合度的结构有8个因素对应于假设尺度。在预期的方向上，APS分量表和“活动测量-疼痛模式”之间发现了高度的相关性。研究2包括111名慢性疼痛患者，旨在检查APS分量表和疼痛适应之间的联系。研究发现，这种活动回避与日常功能和损伤有关。消极情绪与活动回避、过度坚持呈正相关，与任务依存性呈负相关，与积极情绪呈正相关。这项研究表明，APS是一种有效和可靠的临床实践和研究工具。视角：本文为评估慢性疼痛患者的活动模式提供了一种有效和可靠的工具。研究结果表明，回避、坚持和调步是多维结构。区分这些维度有助于揭示先前相互矛盾的结果，并对推荐最适宜的活动模式具有直接的临床意义。(C)2016年度美国疼痛协会
Several self-report measures were used to identify 6 activity patterns in chronic pain patients: pain avoidance, activity avoidance, task-contingent persistence, excessive persistence, pain-contingent persistence, and pacing. Instruments for assessing pacing should include 3 pacing behaviors (breaking tasks into smaller tasks, taking frequent short rests, slowing down), each of which relate to a single goal (increasing activity levels, conserving energy for valued activities, and reducing pain). This article presents the Activity Patterns Scale (APS), which assesses these 6 activity patterns. Study 1 included 291 participants with chronic pain, and tested 3 structures using confirmatory factor analyses. The structure with the best fit had 8 factors corresponding to the hypothesized scales. High correlations in the expected direction were found between the APS subscales and the "Patterns of Activity Measure-Pain." Study 2 included 111 patients with chronic pain, and aimed at examining the association between the APS subscales and adjustment to pain. It was found that that activity avoidance was associated with daily functioning and impairment. Negative affect was positively associated with activity avoidance and excessive persistence, and negatively associated with task-contingent persistence, which was also positively associated with positive affect. This study showed that the APS is a valid and reliable instrument for clinical practice and research.Perspective: This article presents a valid and reliable instrument to assess activity patterns in patients with chronic pain. The findings suggest that avoidance, persistence, and pacing are multidimensional constructs. Distinguishing between these dimensions sheds light on previous contradictory results and has direct clinical implications regarding recommending the most advisable activity patterns.
